Sport at its best is electrifying – but one new game takes the concept a little too literally by allowing players to tackle opponents by zapping them with stun guns.

Ultimate Tazer Ball allows players to zap opponents with 300,000-volt stun guns, to induce a muscle spasm which will make them drop the ball or trip over.

There have been no official games played but the sport’s creators insist it is genuine and claim they are planning to form a league.

Promotional videos have been seen by more than 1million viewers on YouTube.

The game’s US inventors say the stun guns are designed to deliver eight milliamps of current – well below the lethal dose of one amp but enough to test even the legendary ball skills of Barcelona’s Lionel Messi.
